Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across South Houston
Chimney repair in South Houston runs deeper than a quick patch job. Our crews work across the city from the older blocks off Allen-Genoa Road down to the subdivisions near Spencer Highway, and we handle everything from cracked crowns to full flue relining. When Gulf humidity and ship-channel salt air eat at mortar and flashing, the problem compounds fast. We show up in a marked truck, put the price in writing before the first tool comes off the truck, and back every repair with our 365-Day Done Right Promise. Call (830) 251-4560 for a free estimate, and you’ll get a live person on the phone, not a voicemail tree.
Why Flint Chimney Sweep Is South Houston’s Preferred Chimney Repair Company
South Houston homeowners deal with a specific set of chimney problems, and we’ve built our repair process around them. The salt-laden air drifting up from the Houston Ship Channel accelerates corrosion on flashing and masonry in ways you don’t see ten miles inland. We know what that corrosion looks like on a chimney cap, on a crown, and on the mortar joints of a 1960s ranch house near Veterans Boulevard. That local knowledge means we don’t recommend work you don’t need, and we don’t miss work you do.
Every repair from Flint Chimney Sweep follows the same rules, set by Hank Delano and the Garrison Partners family we’re part of: background-checked, uniformed technicians, a written price before any work starts, and the 365-Day Done Right Promise in writing on every job. If a covered repair fails within a year of service, we come back and fix it at no charge. That’s not a courtesy. It’s the guarantee, in writing, on every invoice.
We dispatch from the brand’s Houston office, with crews that work South Houston regularly. That means the team you get knows the local housing stock: the 1950s and 60s brick ranches around College Park, the frame houses near the Pasadena line, the two-story add-ons scattered through the neighborhoods east of Highway 3. You get a repair crew that’s seen your house before, even if you’ve never called us.
Chimney Liner Installation in South Houston
Chimney liner installation in South Houston means replacing or upgrading the inner flue liner that channels smoke, heat, and combustion gases safely up and out of the house. We see old clay tile liners in many South Houston homes, and after decades of Gulf humidity and heat cycling, those tiles crack, spall, or shift. A cracked liner lets heat reach the surrounding masonry and framing, which is how chimney fires start and how carbon monoxide finds its way into living space.
On a 1950s ranch off Park Place Boulevard near the Gulf Freeway, our tech pulled the damper and found the chimney crown cracked and flashing edges pulling away, letting Gulf-driven rain streak the firebox. We replaced the crown, reset the flashing, and dropped a stainless liner with a Copperfield cap; the Level 2 inspection camera also caught light third-degree creosote glazing at the smoke chamber that needed chemical treatment before brushing. That’s a standard South Houston job for us: multiple failures layered on each other, all visible in the photos we send you before we write the proposal.
When a Liner Is Necessary
You need a liner when the existing flue has cracked, when a previous repair left gaps, or when you’re converting a fireplace to a gas insert and the old flue is not rated for it. We inspect interior flue tiles with a Level 2 camera and show you the footage. If the liner can be repaired with a product like HeatShield rather than fully replaced, we’ll tell you that and quote both options. That kind of straight answer is the only kind we give.
Liner Materials We Use
We install stainless steel liners using DuraFlex components, and we stock the connection hardware, caps, and terminations those jobs need. Stainless handles the South Houston humidity better than rigid aluminum, and it holds up to the temperature swings that come with Gulf Coast weather. The liner is sized to the appliance and the existing flue, never one-size-fits-all.
Chimney liner installation in South Houston typically runs $2,200 to $4,600 depending on flue height, liner diameter, and whether we’re also addressing the crown and cap in the same trip. We give you a written price before we start. No surprises on the invoice.
Chimney Flashing Repair in South Houston
Chimney flashing repair in South Houston fixes the metal flashing where the chimney meets the roofline, the point where most chimney-related roof leaks actually start. South Houston’s humid, salt-heavy air corrodes flashing faster than the dry inland heat does. What looks like a roof leak is often a flashing failure: step flashing pulled away from the brick, counter-flashing rusted through, or sealant that a previous contractor smeared over rust instead of replacing the metal.
We don’t caulk over rust. We remove the failed flashing, inspect the underlying decking, and install new flashing using materials matched to the roof and the chimney. When roofers around South Houston patch flashing with tar or caulk, they trap water behind the sealant, which soaks into the mortar and the firebox. We see the result of that shortcut often: spalled brick, water staining in the firebox, and a hidden leak path that’s been active for years. The camera report tells the story.
Flash Flashing Failure Signs
Tell-tale signs in South Houston are water streaks on the ceiling near the chimney after a Gulf-driven rain, rust-colored staining on the brick, and mortar that crumbles when you touch it. If you’ve had a roofer out twice and the leak comes back, it’s not the shingles. It’s the flashing. We’ll show you the photos before we quote.
Repair Scope and Cost
Chimney flashing repair in South Houston typically runs $450 to $1,400. The range covers partial re-flashing on one side up to full replacement of step and counter-flashing around all four sides. We quote the price flat, in writing, before we start. No add-ons at the door.
Trusted Brands We Service in South Houston
We work with chimney components from manufacturers whose engineering we trust: Olympia Chimney for caps and terminations, Famco for dampers and venting, Copperfield for the crowns and caps that stand up to salt air, and DuraFlex for stainless liners. We stock the most common repair parts in our Houston-based inventory, so a South Houston repair doesn’t stall out waiting on a shipped part. When you call, we can usually tell you on the phone which brand applies to your chimney, because we know what’s installed in the housing stock here. That matters when you’re trying to figure out if your existing cap or damper can be matched rather than fully replaced.
Common Chimney Repair Problems We See in South Houston Homes
- Flashing corrosion from ship-channel salt air: South Houston sits close enough to the Houston Ship Channel that airborne salt and industrial grit speed up corrosion on flashing, caps, and even mortar joints. We find step flashing rusted through on chimneys where the roof is otherwise sound.
- Mortar joint deterioration from Gulf humidity: The humid air keeps masonry damp longer each season, which breaks down mortar between bricks. Repointing in South Houston is more often about repairing joints that have lost their binder than about a few cosmetic cracks.
- Leaf litter and grit blocking the flue draft: Tree-heavy lots throughout the city drop debris into uncapped flues, and that debris mixes with creosote to restrict draft. Homeowners sometimes read that as a cold-chimney problem when the real fix is a Copperfield cap and a thorough cleaning.
- Third-degree creosote glazing on older masonry flues: South Houston’s older homes were built with clay tile liners that never fully sealed, and years of wood-burning have left a hard, glassy creosote layer. That glaze cannot be brushed off; it requires chemical treatment before the flue can be safely cleaned and returned to service.

FAQs About Chimney Repair in South Houston
Most South Houston chimneys need a professional inspection every year and a cleaning every one to three years, but the repair interval depends on the chimney’s age and exposure. Flashing and mortar will typically need attention every ten to fifteen years in this humid, salt-touched climate. That’s the pattern we see across South Houston’s housing stock, particularly on 1950s and 60s homes. The honest test is the Level 2 camera report: if the flue liner is intact and the water isn’t getting past the flashing, you’re looking at a cleaning, not a repair. If the camera shows cracked tile or the chimney is pulling away from the roof, that’s a repair we need to schedule. Call (830) 251-4560 and we’ll give you a straight answer after the inspection.
The flat price covers the full repair scope, including labor, materials, and the written 365-Day Done Right Promise. We agree on that price after the inspection, before any repair work starts, and the number you approve is the number on your invoice. If the repair scope changes, you see the new written price before we proceed. There’s no version of our process where you find out the final cost at the door.
Yes, every Level 2 inspection includes camera footage of the entire flue, the smoke chamber, the crown, and the flashing areas, and we’ll walk you through what the images show before we recommend anything. When the leak is coming from failed flashing, you’ll see the rust and the pulled-away metal in the photos. When the issue is a cracked crown, you’ll see the fracture lines. Nothing gets recommended without camera evidence you can review yourself. That’s how the Garrison Standard works: shows the problem, quotes the fix, then does the work.
Third-degree creosote, meaning the hard, glossy glaze that coats a flue after years of wood-burning, can usually be treated chemically and then cleaned without a rebuild. The process uses a chemical treatment that neutralizes the creosote so it can be brushed out. Whether the chimney also needs a rebuild depends on the physical condition of the flue itself, not the creosote layer. We assess both conditions at the same time and give you a separate, itemized recommendation for each. If the liner is cracked, that’s a liner job. If the brick is spalling badly, that’s a rebuild. If it’s just the creosote, that’s a cleaning and treatment. We’ll tell you which applies, with the photos to back it up.
Yes, we install and service chimneys with DuraFlex stainless liners, HeatShield resurfacing systems, Olympia Chimney caps and terminations, Famco dampers, and Copperfield crowns and caps. Our Houston inventory stocks the common parts for these brands, so most South Houston repairs happen in a single visit. We use the brand that matches the job and your existing setup, and we can tell you by phone which brand applies to your chimney. We don’t push a brand because it’s in stock; we push the brand that fits the repair.
If your South Houston chimney needs a repair, a second opinion, or a straight answer about what’s actually wrong, call (830) 251-4560. You’ll reach a live person. We’ll schedule the inspection, send a background-checked technician, and put every recommendation in writing before you spend a dollar. That’s the way a chimney company should work, and it’s the only way we do.
